是否可以在UIAlertView中添加图像,例如从plist文件中显示图像?
你可以这样做:
UIAlertView *successAlert = [[UIAlertView alloc] initWithTitle:title message:message delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(220, 10, 40, 40)];
NSString *path = [[NSString alloc] initWithString:[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"smile.png"]];
UIImage *bkgImg = [[UIImage alloc] initWithContentsOfFile:path];
[imageView setImage:bkgImg];
[successAlert addSubview:imageView];
[successAlert show];
这将在你的警告框右上角添加一张图片,你可以更改框架图像来移动它。
希望这有所帮助。
在 iOS 7 或更高版本中,请使用以下代码:
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 200, 282)];
UIImage *wonImage = [UIImage imageNamed:@"iberrys.png"];
imageView.contentMode=UIViewContentModeCenter;
[imageView setImage:wonImage];
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Arirang List"
message:@"phiên bản: 1.0\n website: www.iberrys.com\n email: quangminh@berrys.com\nmobile: 0918 956 456"
delegate:self
cancelButtonTitle:@"Đồng ý"
otherButtonTitles: nil];
//check if os version is 7 or above
if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
[alertView setValue:imageView forKey:@"accessoryView"];
}else{
[alertView addSubview:imageView];
}
[alertView show];
UIAlertView *Alert = [[UIAlertView alloc] initWithTitle:@"your Title" message:@"Your Message" delegate:nil cancelButtonTitle:@"Your Title" otherButtonTitles:nil];
UIImageView *image = [[UIImageView alloc] initWithFrame:CGRectMake(0,0, 40, 40)];
NSString *loc = [[NSString alloc] initWithString:[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"Your Image Name"]];
UIImage *img = [[UIImage alloc] initWithContentsOfFile:loc];
[image setImage:img];
if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
[Alert setValue:image forKey:@"accessoryView"];
}else{
[Alert addSubview:image];
}
[Alert show];
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 200, 282)];
UIImage *wonImage = [UIImage imageNamed:@"iberrys.png"];
imageView.contentMode = UIViewContentModeCenter;
[imageView setImage:wonImage];
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Arirang List"
message:@"phiên bản: 1.0\n website: www.iberrys.com\n email: quangminh@berrys.com\nmobile: 0918 956 456"
delegate:self
cancelButtonTitle:@"Đồng ý"
otherButtonTitles:nil];
//check if os version is 7 or above
if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
[alertView setValue:imageView forKey:@"accessoryView"];
} else {
[alertView addSubview:imageView];
}
[alertView show];
注意:适用于iOS 7及以上版本
if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
[alert setValue:imageView forKey:@"accessoryView"];
}else{
[alert addSubview:imageView];
}
Swift版本:
let alertView = UIAlertView(title: "Alert", message: "Alert + Image", delegate: nil, cancelButtonTitle: "OK")
let imvImage = UIImageView(frame: CGRect(x: 0, y: 0, width: 100, height: 100))
imvImage.contentMode = UIViewContentMode.Center
imvImage.image = UIImage(named: "image_name")
alertView.setValue(imvImage, forKey: "accessoryView")
alertView.show()
我对Madhup提供的解决方案进行了一些修改。
Madhup的解决方案适用于短消息,但是当消息过长时,消息将被图像覆盖。
因此,我在UIAlertViewDelegate方法中添加了以下步骤- (void)willPresentAlertView:(UIAlertView *)alertView
在消息前添加8个"\n",将消息向下推,为图像保留空间(我的图像受到100x150的限制)
检测AlertView的子视图,查找UITextView是否存在。
只有当消息过长时,UITextView才会存在。
如果UITextView不存在,则一切都很好,图像显示良好,消息显示良好。
如果UITextView存在,则从UITextView.text中删除8个前缀"\n",然后调用UITextView.setFrame来调整UITextview的大小和位置。
上述操作效果良好。
我发送一个NSDictionary作为要显示的消息,该字典包含2个键值对,“msg”=>真实消息字符串。“url”=>作为来自网站的图像。
使用NSURLConnection的sendSynchronousRequest方法,代码将从互联网中获取图像数据。- (void)showAlertView:(NSDictionary *)msgDic {
NSLog(@"msgDic = %@", msgDic);
NSMutableString *msg = [[NSMutableString alloc] initWithString:@"\n\n\n\n\n\n\n\n"];
if ([msgDic objectForKey:@"msg"]) {
[msg appendFormat:@"%@", [msgDic objectForKey:@"msg"]];
}
else {
[msg setString:[msgDic objectForKey:@"msg"]];
}
NSLog(@"msg = %@", msg);
UIAlertView* alert = [[UIAlertView alloc] initWithTitle:@"Alert Title"
message:msg
delegate:self
cancelButtonTitle:@"Close" otherButtonTitles:nil];
if ([msgDic objectForKey:@"url"]) {
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:[msgDic objectForKey:@"url"]]];
[request setCachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData];
NSData *imgData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
if (imgData) {
UIImage *shownImage = [UIImage imageWithData:imgData];
UIImageView *imgView = [[UIImageView alloc] initWithImage:shownImage];
[imgView setFrame:CGRectMake(floor(284-100)/2.0, 47, 100, 150)];
[alert addSubview:imgView];
[imgView release];
}
}
alert.delegate = self;
[alert show];
[alert release];
[msgDic release];
}
- (void)willPresentAlertView:(UIAlertView *)alertView {
int viewCount = [alertView.subviews count];
NSLog(@"subviews count = %i", viewCount);
if (viewCount > 0) {
BOOL bFoundTextView = NO;
for (int count=0; count<=[alertView.subviews count] -1; count++) {
BOOL bIsTextView = NO;
UIView *subView = [alertView.subviews objectAtIndex:count];
NSLog(@"view index %i classname = %@", count, [[subView class] description]);
bIsTextView = [[[subView class] description] isEqualToString:@"UIAlertTextView"];
bFoundTextView |= bIsTextView;
if (bIsTextView) {
UITextView *textView = (UITextView *)subView;
NSMutableString *msg = [[NSMutableString alloc] initWithString:textView.text];
[msg setString:[msg substringFromIndex:8]];
textView.text = msg;
CGRect frame = textView.frame;
if (frame.origin.y != 205) {
frame.origin.y = 205;
frame.size.height -= 155;
[textView setFrame:frame];
}
[msg release];
}
}
}
}
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Hello"
message:nil
preferredStyle:UIAlertControllerStyleAlert];
UIImage *image = // target image here;
CGSize size = image.size;
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(leftMargin, topMargin, size.width, size.height)];
